It is the same, at bottom, with his professional work. He protects the intellectual freedom, as it were, of his students with the same jealousy as he protects his own. There shall be no oratorical device, no persuading, no cajoling of the mind this way or that. “A professor is the priest of his subject, and should do the honors of it gravely and with dignity.” And so the man who in his private Journal is master of an eloquence and a poetry, capable of illuminating the most difficult and abstract of subjects, becomes in the lecture-room a dry compendium of universal knowledge. “Led by his passion for the whole,” says M. Scherer, “Amiel offered his hearers, not so much a series of positive teachings, as an index of subjects, a framework--what the Germans call a _Schematismus_. The skeleton was admirably put together, and excellent of its kind, and lent itself admirably to a certain kind of analysis and demonstration; but it was a skeleton--flesh, body, and life were wanting.” So that as a professor he made no mark. He was conscientiousness itself in whatever he conceived to be his duty. But with all the critical and philosophical power which, as we know from the Journal, he might have lavished on his teaching, had the conditions been other than they were, the study of literature, and the study of philosophy as such, owe him nothing. But for the Journal his years of training and his years of teaching would have left equally little record behind them. “His pupils at Geneva,” writes one who was himself among the number, [Footnote: M. Alphonse Rivier, now Professor of International Law at the University of Brussels.] “never learned to appreciate him at his true worth. We did justice no doubt to a knowledge as varied as it was wide, to his vast stores of reading, to that cosmopolitanism of the best kind which he had brought back with him from his travels; we liked him for his indulgence, his kindly wit. But I look back without any sense of pleasure to his lectures.”
